Well maybe not, Mr Johnson.
This afternoon MPs used the NI Bill as a means to try to prevent Johnson from proroguing parliament. They did it via an amendment and it was passed 315 to 274 - a majority of 41. It was a dirty trick to use, but then dirty tricks (prorogation) sometimes need dirtier tricks to combat them.
Another defeat on a related issue came from the HoL 315 - 273.
The results do not directly prevent the prorogation of parliament, but the numbers are very interesting regarding the business.
Ministers Hunt and Bradley were paired so did not vote along with two other opposition MPs. Ministers Hammond, Gauke, Clark and Stewart voted against the government. Some 30 Tory MPs abstained and another 17 voted against. That cohort represents about 20% of the Tory parliamentary group of MPs and could be boosted by maybe 12 more from cabinet once the reshuffle is done.
It's a strong shot across the bows of the incoming PM. Odds for an early no confidence vote: 12/5.
